Why is salt bad for shoes? What happens if they go untreated?

Salt can wear out leather prematurely. If left untreated, it can discolor and weaken the finish of your shoes. A thin layer of wax polish between the leather and harmful elements like salt (or even sand and lime) could be the difference between a quick and easy cleaning versus a lengthy and costly trip to a shoe repair specialist. Always use KIWI®polish and protectors to protect your shoes from the elements.
